1987～1988年对一个村的肠道蠕虫卵阳性者进行了6次化疗,使人群肠道蠕虫感染率下降68.70％。通过900份土样分离虫卵调查,实验村阳性率(28.67％)显著低于对照村(72.00％)(p<0.001),且前者土壤中的虫卵密度也低于后者。提示,对肠道蠕虫感染者反复查治可以减少虫卵对外界环境的污染,控制肠道蠕虫病的流行。
From 1987 to 1988, 6 chemotherapy treatments were given to intestinal worm-positive in a village, which reduced the intestinal worm infection rate by 68.70%. The results showed that the positive rate (28.67%) in the experimental village was significantly lower than that in the control village (72.00%) (p <0.001). The egg density in the former soil was also lower than the latter. Tip, repeated investigation of intestinal worms infection can reduce the pollution of eggs on the environment, control the prevalence of intestinal helminths.
